JOHN W. WOOLEY, OF NORFOLK, VIRGINIA.

SHUTTER-WORKER.

Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed September 25. 1907. Serial No. 394.474.

To all whom it may concern:

Be it known that I, JOHN W. WOOLEY, a citizen of the United States,residing at Norfolk, Berkley Station, in the county of Norfolk and Stateof Virginia, have invented a new and useful Shutter-Worker; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The invention relates to improvements in shutter-workers, and has forits object to provide a simple, inexpensive and durable device of thischaracter adapted to be applied to any kind of shutter and which willenable the shutter to .be opened or closed from the interior of thehouse and without touching the windows.

In the drawings, Figure 1 is a side elevation of my invention shownapplied to a shutter. Fig. 2 is a detail sectional view taken throughthe operating bar. Fig. 3 is a perspective view of the upper hinges.Fig. 4 is a view showing the blank from which, one member or leaf ofeach, of the lower hinges is formed.

Referring to the drawings, 1 designates an operating bar, having a knob2 arranged on the interior of a house, and extending outwardly to theexterior thereof. The inner end of the bar 1 is provided with notches 3which are engaged by a locking member 4 for holdin said bar in itsdesired adjustment, as wilI be clearly understood. The outer end of bar1 is provided with notches or cogs 5, which engage a cylindrical member6 which is inte ral with the hinge 7 of the shutter.

, The cy indrical member 6 is hollow as shown and is provided withvertical slots 8 which form co s 9.

It wil be seen that by thrusting the bar outwardly the shutters willopen and by drawing it inwardly the same will be closed.

The upper portion of the shutter is provided with a pair of L-shapedhinges 10 which are connected by a pivot bar 11.

The hinges 10 are provided with openings 12, so that they can be used toreceive the operating bar 1, when desired.

As disclosed particularly by Fig. 4, each lower hinge member 6, 7 isformed from a piece of malleable metal or blank in its initial formrectangular in general outline, with apertured lateral extensions orwings 13 at or near one end, it being produced in its longitudinalcenter with the rectangular or oblong perforations or slots 8 formingthe prospective cog-like members 9, said slots and cog-members beingboth above noted. Said blank or metal piece is, rolled upon itself fromthe left-hand end into cylindrical form said end having a projection orextension 14 which is inserted or tucked into a slot 15 also formed inthe blank for its reception, said extension or projection being finallyclenched or bent down upon the opposite surface of the blank. The wingsor extensions 13 of said metal piece or blank, are next bent down atright angles to their initial position, and thus caused to form heads orends w for the resulting cylinder-member 6 whose apertures receive thehinging or pivoting pintle of the other hinge member, as will be readilyappreciated.

WVhat is claimed is,

A device as described, embracing a hinge one of Whose members or leaves,is formed from a blank, rectangular in general outline with aperturedlateral extensions or wings at or near one end, said blank also havingtransverse slots in its longitudinal center and rolled upon itself incylinder form, with said slots forming cog-like members therein, saidwings being bent upon, and forming apertured heads for the resultingcylinder, and a rack bar adapted to engage said cog-like members orslots of said cylinder of said hinge member.

In testimony whereof Ihave signed my name to this specification in thepresence of two subscribing witnesses.

JOHN W. WOOLEY. Witnesses:

A. T. BURNS, H. L. FRANO.
